3.4.3 Combustion system
The combustion furnace is a resistor-heated furnace for combustion temperatures
between 700 °C and 1100 °C. Its tilt device is easy to operate and allows the user to
quickly change between the operating modes.

The default setup of the multi X 2500 basic device uses an open combustion tube. This
combustion tube is used for the following analyses:
 AOX determination in vertical operating mode (recommended)
 POX determination
A quartz glass wool plug is located in the bottom of the combustion tube. The quartz
glass wool filters ashes and soot from the measuring gas stream. When inserting the
quartz container, the plug cushions and prevents damaging the quartz glass.

The combustion tube can take a maximum of 40 quartz containers (depending on
their size and the method employed). When reaching the maximum amount, the user
must wait until the combustion tube has cooled down and empty it.
